hi i have a HP 5300C, connected to a freebsd machine. i patched the kernel so it would recognize the scanner with the usscanner driver to do scsi over usb, instead of the default uscanner driver. however, with the default sane installation this still does not work, saying the requested IO buffer size exceeds DFLTPHYS.
i have been hacking around in sane-backend, mainly in the avision driver. it got rid of the DFLTPHYS error by changing the "used_lines" variable in the avision driver so it would provide a buffer that fits within DFLTPHYS. this apparently was in the code already, but commented out. the scanner output from xsane is still garbage, however. if you look at the scaner while it is trying to scan, you see that the light beam never moves down through the entire scanner. i figure i probably messed something up after making the previous change in the avision driver. anyone ran into this problem before? and solutions? thanks benjie -- benjie chen [email protected]
